Abstract:

We demonstrate a new strategy for the growth of spiral Cd(OH)2 with 1D nanostructure, yielding an average length of 1—3 μm and width up to 30—100 nm, in one-step process via microwave heating approach. The individual spiral nanowire is made of several smaller nanorods that are aggregated into a bundle. The size of diameter and length of the spiral nanowires are readily tunable by modifying the concentrations of the reactants. Different cadmium salts have more influence on the structure and morphology of the obtained products. The formation mechanism of the spiral Cd(OH)2 nanowires was discussed. This method may offer an elegant route for the direct growth of metal hydroxide nanowires with potential implications for attachment to electrodes for novel functional devices.

Key words: Microwave heating approach; Cd(OH)2; Spiral nanowire
